The old JSC JIT optimizes strict equality (===) by having a fast path for when one operand is not a cell, and neither operand is a number. The DFG JIT only has fast-path optimizations for strict equality that speculate that both operands are integers. The DFG JIT should have similar optimizations to the old JIT for strict equality.
